DocLocScreenshotTestCase does not save failure screenshots

[aartikov]

Steps to reproduce:

1. Change kaspressample.docloc_tests.ScreenshotSampleTest to make it failing.
2. Run the test.
3. Open "sdcard/screenshots/en" in Device File Explorer.

Expected behavior: "fails" directory contains a failure screenshot.

Actual behavior: "fails" directory is empty. Logcat has java.lang.IllegalArgumentException: Could not find test class!

Tested on Emulator API 26, x86_64.

@aartikov Hi!
Is the issue actual?

Hi, @aartikov! Indeed, current approach with TestRule doesn't work for several reasons. Right now you could fix it by adding ScreenshotStepWatcherInterceptor interceptor to your test case constructor e.g.

Kaspresso.Builder.simple().apply {
    stepWatcherInterceptors.add(ScreenshotStepWatcherInterceptor(screenshots))
}

There's a PR that aims to take "fail" screenshots out of the box
